[Qemu-devel] [PATCH v3 11/35] cputlb: move CPU_LOOP() for tlb_reset() to exec.c |
Date: |
Sat, 18 Jul 2015 02:40:21 -0700 |
To prepare for multi-arch, cputlb should only have awareness of one
single architecture. This means it should not have access to the full
CPU lists which may be heterogeneous. Instead, push the CPU_LOOP() up
to the one and only caller in exec.c.

Easier reading with git diff -w
Changed since RFCv2:
split off to new patch (previously part of core virtualisation patch)
